For future reference for interested parties, I had saved a Class II hitch from my '90 Electra wagon. Just installed it on my '94 Roadmaster wagon and it fit perfectly. Just had to enlarge four holes on the rear bumper support, to accommodate the larger rear hitch support bolts (This also had to be done on the '90). It also has the advantage of providing the heavy-dutiest backup gas tank straps you'll ever find!
